【摘要】 针对基于数字键盘的语句级拼音汉字输入技术,提出了键音转换问题,并给出了解决方案.首先,形式化地定义了键音转换问题,并根据Bayes原理推导出两种键音转换处理模型.然后将键音转换问题转化为有向无环图的路径搜索问题,根据两种处理模型,分别描述了搜索空间并定义了搜索算法.实验结果表明提出的算法能够有效地解决该问题.更多还原

【Abstract】 For Chinese phonetic input technique on digit keyboard,this paper puts forward the key-to-pinyin-conversion problem and then proposes effective solutions.Firstly,we give the formalized definition of key-to-pinyin-conversion problem and then manage to deduce two models according to Bayes’ rule in order to solve that problem.After that,the problem is transferred to find an optimal road in a direct acyclic graph(DAG).The search spaces and algorithms are described respectively for each deduced model.Experiments results prove that key-to-pinyin conversion problem is a bottleneck for Chinese phonetic input technique on digit keyboard,and our algorithms can effectively solve the problem.更多还原
